No idea, but a google search led me to the following page ....

https://www.gistpianocenter.com/blog/tag/roland-lab/

Once on the page, search for mobilesheets...

Or as Geoff said, try it at a shop. 
There is a free version of Mobilesheets that is limited in the number of songs it can contain, but is fullly functional. So that could be used for testing.

Thx for the search, I found that page too, but since they list other apps it could be they where just listing them up without actually trying them. 

Thx anyway. I'll see if I can get someone's iPad and try it.
